Aliens :storyboard showing Ripley and Newt first encountering the Alien Queen

and

Alien: Alien Stage 3 , version III, Side view (work 372) and front view (work 373) (1978) by HR Giger

 

 

a) The head of Giger's alien beast along with the shoulder fins have been turned into the crouching alien queen form suspended in the air, with the front of the dome becoming her head and the shoulder fins becoming her legs, while the ribcage becomes the front of her egg laying sack. 

b) What we might also notice is just as Giger painted the right side of the ribcage and the right shoulder, so Cameron transformed the right side of the chest and right arm into the egg laying sack
